Princess range of products fulfills the highest quality standards and is characterised by absolute safety, as a result of applying an elaborate and unique purification method which removes all undesired compounds from the gel. Princess contains reticulating agent residuals below the detection limit (<1 ppm).

Princess products were created using revolutionary, patent-protected S.M.A.R.T. technology (Supreme Monophasic and Reticulated Technology). Only pure and natural hyaluronic acid of biofermentative origin is used as a basis for the S.M.A.R.T. synthesis. The S.M.A.R.T. process uses the well-established BDDE (butanedioldiglycidether) as reticulating agent to create a very dense HA network and perfectly clear gel consisting of very long, strong and stable chains of hyaluronic acid.

The last stage of S.M.A.R.T. process is the removal of oxygen molecules, which enhances the stability of the gel once it is filled into the syringe, thus guaranteeing absolute safety of the procedure and full control over its results. Princess fillers are monophasic, complex and viscoelastic, which makes them perfectly smooth and highly elastic at the same time.
